I apologize for replying to my own message, but I discovered another workaround:
In the Pydev Python interpreter preferences, if I add a new "Forced
Builtin" named "zope" then the following line works (where it didn't
previously):
from zope import sqlalchemy
This workaround may be preferable to using CTRL+1 to ignore the
Unresolved import because it enables code completion/suggestion and
"jump to source" to work.
This workaround doesn't seem particularly "clean" to me though, and
I'd much prefer for PyDev imports to work in a manner consistent with
the Python Interpreter invoked from the shell.
Thanks.
